A Russian anti-satellite test sparked an orbital-debris emergency aboard the International Space Station today, followed by sharp protests from NASA’s administrator and other U.S. officials.
The incident, which involved the deliberate destruction of a one-ton Russian spy satellite known as Cosmos 1408, is likely to spur renewed debate over military rules of engagement in space and the nature of Russian (and Chinese) anti-satellite maneuvers.
The U.S. Space Command said Russia struck Cosmos 1408 with a direct-ascent, anti-satellite missile, breaking it into more than 1,500 pieces of trackable orbital debris and what’s thought to be hundreds of thousands of smaller bits.
“The debris created by Russia’s DA-ASAT will continue to pose a threat to activities in outer space for years to come, putting satellites and space missions at risk, as well as forcing more collision avoidance maneuvers,” U.S. Army Gen. James Dickinson, commander of the Space Command, said in a news release. “Space activities underpin our way of life, and this kind of behavior is simply irresponsible.”
The trajectories for the debris cloud and the International Space Station come close to each other every 90 minutes, and that required the space station’s seven crew members to take cover today.
